See below:

Step-by-step explanation:

At x axis intercepts, the value of y = 0

0 = -3/5 ( x+7)^2   + 6

-6(-5/3) =   (x+7)^2

 10 = (x+7)^2

x =  -7 +- sqrt (10)

Answer:

[tex] x = -7 \pm \sqrt{10 [/tex]

Step-by-step explanation:

The x-intercepts occur where y = 0.

-3/5(x + 7)² + 6 = 0

-3(x + 7)² + 30 = 0

-3(x² + 14x + 49) + 30 = 0

-3x² - 42x - 147 + 30 = 0

3x² + 42x + 117 = 0

[tex] x = \dfrac{-42 \pm \sqrt{42^2 - 4(3)(117)}}{2(3)} [/tex]

[tex] x = \dfrac{-42 \pm \sqrt{360}}{6} [/tex]

[tex] x = \dfrac{-42 \pm 6\sqrt{10}}{6} [/tex]

[tex] x = -7 \pm \sqrt{10 [/tex]

Step-by-step explanation:

the volume of a figure bases always on a calculation that multiplies 3 dimensions.

while a surface area bases always on a calculation that multiplies 2 dimensions.

since the figures are similar, that means that all dimensions or side lengths of one figure correlate to the corresponding dimensions or side lengths of the other figure via the same scale factor f.

and that means that

large side length = small side length × f.

and that means that f has to be multiplied in 3 times for the volume and 2 times for the surface area (once for every dimension).

so,

large volume = small volume × f × f × f =

= small volume × f³

1536 = 648 × f³

f³ = 1536/648 = 64/27

f = 4/3

and

large surface = small surface × f×f =

= small surface × f²

small surface = large surface / f² = 864 / 16/9 =

= 864 × 9/16 = 54 × 9 = 486 m²

The money account is doubled at an interest rate of 5.2 % compunded quarterly, that is, under the model of compound interest in a time period of about 3.5 years.

The compound interest takes into account the change of money deposited in time in contrast with the simple interest, which only takes the initial amount of money into account. Please notice that four quarters equals a year.

The compound interest formula is described below:

C = C' · (1 + r/100)ⁿ     (1)

Where:

If we know that C = 2 · C' and r = 5.2, then the doubling time is:

n = /㏒ C/C'/㏒ (1 + r/100)

n = ㏒ 2/㏒ 1.052

n ≈ 13.674

Step-by-step explanation:

[tex]\frac{3x^2-3}{x^2-5x+4}[/tex] ( factorise numerator and denominator )

3x² - 3 ← factor out 3 from each term

= 3(x² - 1²) ← x² - 1 is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

x² - 1

= x² - 1²

= (x - 1)(x + 1) , then

3x² - 3 = 3²(x - 1)(x + 1) ← in factored form

--------------------------------

x² - 5x + 4

consider the factors of the constant term (+ 4) which sum to give the coefficient of the x- term (- 5)

the factors are - 1 and - 4 , since

- 1 × - 4 = + 4 and - 1 - 4 = - 5 , then

x² - 5x + 4 = (x - 1)(x - 4)

Here,

→We get 1620 products every 30 seconds

→We get 1620/30=54 products in every 1 second

→We get 54×60=3240 products in every 60 seconds(1 minute)

As we have

60seconds=1min

60 minutes=60 seconds ×60

Now,

→We get 3240×60=194400 products in every 60 minutes

Also,

→We get 450 products every 7 seconds

→We get 450/7=64.28 products in every 1 second

Answer:

6

Step-by-step explanation:

There is no perfect square root of 40 but when calculated it would be 6.33 which rounds down to 6.

Answer:

Step-by-step explanation:

Given points P(4, 2) and Q(13, 14), you want the length of PQ and its midpoint.

The length of PQ is given by the distance formula ...

  d = √((x2 -x1)² +(y2 -y1)²)

  d = ((13 -4)² +(14 -2)²) = √(9² +12²) = √225

  d = 15

The length of PQ is 15 units.

The midpoint is halfway between the end points. It is conveniently found as the average of the coordinates of the end points.

  M = (P +Q)/2

  M = ((4, 2) +(13, 14))/2 = (4+13, 2+14)/2 = (17, 16)/2

  M = (8.5, 8)

The midpoint of PQ is M(8.5, 8).

Additional comment

The length of PQ is the hypotenuse of a right triangle with side lengths 9 and 12 units. You recognize this ratio as 3:4, so the triangle is a 3-4-5 right triangle, scaled up by a factor of 3. The length PQ is 3·5 = 15.

{3, 4, 5} is one of several Pythagorean triples commonly seen in textbook problems. Others include {5, 12, 13}, {7, 24, 25}, {8, 15, 17}.

Answer:

136

Step-by-step explanation:

First you multiply 7•5 which is 35, and sense there is 2 squares with that unit, you multiply 35•2 which is 70. After that you get the middle value by multiplying 6•7, which is 42. Then you add 42+70, and that's 112. Now you have to find the area of the triangle, so you multiply 6•4, and that's 24, but sense there are 2 of them with the same unit you don't need to divide by 2. Then after that you add 112+24 and the total area is 136

Answer:

  136 square units

Step-by-step explanation:

A "net" is a map of the surfaces of the prism. If you cut it out and fold along the solid lines, you can shape it into the triangular prism it represents. The area of the net is the area of the prism.

As with any composite figure, its area can be found by decomposing it into parts whose area formulas you know. Here, the net can be cut along the horizontal lines to form a rectangle and two triangles.

__

The rectangle has an overall length of 5+6+5 = 16 units, and a width of 7 units. Its area is ...

  A = LW

  A = (16)(7) = 112 . . . . square units

Each triangle has a base of 6 units and a height of 4 units. Its area is ...

  A = 1/2bh

  A = 1/2(6)(4) = 12 . . . . square units

The composite figure shown has been decomposed into one rectangle and two triangles, so its total area is ...

  rectangle area + 2 × triangle area

  = 112 + 2×12 = 136 . . . . square units

The surface area of the triangular prism is 136 square units.

Answer:

4n-10, Answer is D

Step-by-step explanation:

First we will use n as any number.

the difference between each of the numbers is +4

This creates first part of the formula.

4n...

If you do 4n and replace n as one (For the first number of the sequence) then 4×1=4. You then have to find out how much you need to add or subtract to get -6 so the difference between 4 and -6 is -10.

This creates the second part of our formula.

4n - 10

You can check this by doing the same thing for the second number and replacing n with 2.

2×4=8

8 - 10= -2 which is the second number in the sequence which confirms this is correct.

If Faleye Consulting’s WACC is 10% and both “projects” can be repeated indefinitely, the system that should be chosen is System A, and its EAA is $2,866.91.

The EAA of a project is the Equivalent Annual Annuity.  The EAA can be determined using the following formula.

EAA = r x NPV1 - (1 + r)-n

Where the EAA = Equivalent Annual Annuity

r = interest rate per period

n = project duration

NPV = Net present value of project

We can also compute the EAA by using an online finance calculator as follows:

                                                System A        System B

After-tax cost                           $19,000         $13,000

After-tax cash flows                 $6,000           $6,000

Equipment duration                 6 years           3 years

WACC = 10%

Annuity factor                            4.355              2.487

Present value of cash flows $26,130          $14,922 ($6,000 x 2.487)

NPV                                          $7,130           $1,922 ($14,922 - $13,000)

EAA (an online calculator)    $2,866.91        $800.966

Thus, using the EAA rule, the computer system that should be chosen is System A because it has a higher EAA than System B.
